  [mlir][spirv] Lower mapped TOSA custom ops to ExperimentalML.Call (#202581)

Extend the TOSA to SPIR-V Graph conversion with an optional
custom-op-domain-to-opcode mapping. TOSA custom ops whose domain appears
in this mapping are lowered to spirv.ExperimentalML.Call using the
mapped CALL opcode. Later mappings for the same domain override earlier
ones, matching command-line option precedence.

For this TOSA lowering, CALL operands start with a spirv.array<N x i8>
carrying the operator_name byte blob. This is followed by another i8
array for implementation_attrs, then the original tensor inputs. Empty
strings are encoded as a single NUL byte because SPIR-V array types
require at least one element.

Use existing SPIR-V array constants for the metadata operands so the
target test stays on the SPIR-V binary round-trip path.
